Request InfoHamamatsu CorporationHamamatsu Photonics K.K.’s Electron Tube Div. has introduced a photomultiplier tube with enhanced UV sensitivity. The R11540 is a 28-mm-diameter side-on device with a spectral response ranging from 185 to 760 nm. It produces 40% quantum efficiency at 350 nm and anode sensitivity of 11.3 x 105 A/W at 350 nm and 12 x 105 A/W at 420 nm. Its sensitivity and high gain of 1 x 107, typical, make it suitable for low-light detection of UV and visible light in fluorescence spectrometers. It also can be used as a fluorescence detector for high-performance liquid chromatography, as a sulfur dioxide...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Mar/Apr 2024 IssueMulti-LED for WearablesThe SFH 7018 is a red/green/IR LED package from ams OSRAM that can make photoplethysmography (PPG) measurements in smart watches, wristbands, and other wearable devices.
